Charlie saves $80.
Bryan saves 8 times as much money as Charlie.
- How much does Bryan save?
- How much does Bryan save more than Charlie?
- How much does Charlie save less than Bryan?
- How much do both of them save altogether?
(a)
Focus on the sentence with the word 'times'.
Assign 1 u to the variable that is found after the word 'times'.
Amount that Charlie saves = 1 u
Amount that Bryan saves = 8 u
1 u = 80
Amount that Bryan saves
= 8 u
= 8 x 80
= $640
(b)
Amount that Bryan saves more than Charlie
= 8 u - 1 u
= 7 u
= 7 x 80
= $560
(c)
Amount that Charlie saves less than Bryan
= 8 u - 1 u
= 7 u
= 7 x 80
= $560
(d)
Total amount that both of them save altogether
= 1 u + 8 u
= 9 u
= 9 x 80
= $720
Answer(s): (a) $640; (b) $560; (c) $560; (d) $720
